I'm afraid we have no examples for the protocol. Do you really need to drive the device directly? There is a C example for the PT104 using the windows DLL. This API is much more simple to use.

The driver is not signed for XP.

Windows may reject any unsigned drivers depending on the current system policy. This can be changed in System Properties | Hardware | Driver Signing.

Its not possible to do this with the ADC212.

The PicoScope 2205 and PicoScope 5000 series have more advanced trigger logic so that you can trigger A AND B or A OR B. However, I dont think these products would entirely satisfy your requirements as they do no trigger counting.

When you open the device you can pass USBADC11_BATCH_AND_SERIAL to UsbAdc11GetUnitInfo to query the device serial number. The serial numbers are also printed on the USB ADC11 so you can tell which is which.

I dont think that you will need to implib the dll to get the lib file. You should be able to use pt10432.lib directly. The difference between pt10432.lib and pt104ms.lib is that the latter uses name decoration. As far as I know, Borland uses undecorated names when linking should you will need to use...

Hi Frog

Delete the line CatalogFile=picopp.cat and it should allow you to install the device drivers on 98.

A modulus probe would use a look up table to define its behaviour similar to the one below: -2V 2V 0V 0V 2V 2V If you input a sine wave into this probe it will give an output like the image below. Hopefully you can now see that the inverse scaling would yeild more than one trigger point which is imp...

How would you 'fix' this problem for the modulus probe that I described earlier?

The scope cannot trigger at more than one threshold. It would be even more confusing to have different behaviour for probes that have multiple solutions to their inverse scaling.

You are quite correct. PicoScope 6 does behave differently to PicoScope 5 in this instance. PicoScope 5 cannot create custom probes and as such does not suffer from the problem that I described in my earlier post.

The threshold displayed on the trigger toolbar is the threshold set after your x10 probe has been applied. When you drop your trigger point onto the scope at 800mV, the inverse of the probe scaling is applied and the scope is configured to trigger at 80mV. It is easy to imagine a probe that could ha...

It is possible to do a silent install using our installer but it would mean that you would need a ~27MB installer to deploy only ~340kB of files. You only require three files to deploy the drivers yourself: 1) in your application directory: usbtc08.dll 2) C:\windows\system32\drivers\picopp.sys 3) C:...
